I have installed a new Pioneer DVR-109BK. No matter what I do I cannot get it to read any type of DVD. I have tried blank DVD's (Ritek and Taiyo-Yuden). I have also tried movie DVD's as well as DVD's with data rather than movie files. None of the foregoing will work. I do have other DVD players on my computer and they read all of the foregoing disks just fine. I have also updated to the latest firmware (1.09) with no success. Strangely enough, the player will read and play CD's just fine (it just won't read or play a DVD of any kind). Any suggestions as to what I can do to resolve this? I have also requested help on this issue through Pioneer's website. Thanks in advance. Thank you in advance for your help. Brian.
